Key Questions:

1. How does temperature and pH affect the activity of enzymes?
   • Temperature affects enzyme activities by decreasing its activity either side of the optimum pH.
2. How do you calculate a rate of reaction?
   • The rate of reaction is calculated by the reactant used or product made divided by time.
3. What is the most important part of the enzyme with regartds to its shape?
   • The most important part of an enzymes structure is the active site.
4. The binding of the substrate with the active site is known as what theory?
   • The binding of the substrate with the active site is known as the Lock and Key theory.
5. Where are amylase, protease and lipases created in the body?
   • Amylase is produced in the saliva/mouth, pnacreas and small intestine. Protease is produced in the stomach, pancreas and small intestine. Lipases are produced in the pancreas and small intestine.
6. Why are enzymes needed in digestion?
   • Enzymes are needed in digestion to convert food to small soluble molecules that can be absorbed into the bloodstream.
7. What do carbohydrases break carbohydrates down to?
   • Carbohydrases break carbohydrates into simple sugars.
8. What does the carbohydrase amylase break down?
   • The carbohydrase amalyse breaks down starch in sugars.
9. What do proteases break proteins down into?
   • Proteases break down proteins into amino acids
10. What do lipases break fat/lipids down into?
    • Lipases break down fat/lipids into fatty acids and glycerol
